Japan
From June 10, Japan is now open for tourists and areas designated as ‘blue’ countries like Hong Kong will be able to enter through package tour bookings. Quarantine and arrival testing has been eliminated for Hongkongers, and Covid-19 vaccine is not required. But we still need to apply for a visa, which may take time to process. If you’re planning to go on a solo sojourn, unfortunately, independent tourists cannot enter yet. Aside from booking small package tours with a complete itinerary for the whole duration of the tour, a negative PCR test must be submitted 72 hours before departing for Japan. Upon arrival, tourists will be required to fill in a questionnaire with their travel details, and then you can enter without quarantining or doing a PCR test.
